Servo Horn for Dymond D47 Servo (2mm holes for M2 screws)

I needed a custom horn for my Dymond D47 servo, so I took a picture of another horn and loaded it into Fusion360, and then did my best to trace out what I think would be an appropriate fit.

Then, I created my own horn will fit directly onto the existing Dymond D47 servo and can remain attached by using the tiny screw that already comes with the Dymond D47.

The new horn has 2 holes that will allow an M2 screw to pass through.

This print requires using an SLA printer. Layer height doesn't matter (I used 0.1mm layer height).

It is best to print it flat, as-is in the STL file, because that way you get the best accuracy for the little point indentations that need to fit around the Dymond D4's white spline/horn attachment piece. Of course, you can (and should) use auto-generated supports as well so that it's easier to remove from the build platform.

It was a reasonably snug fit for me using Formlabs Grey Pro resin at .100mm layer height.
